useful Improvements in Auxiliary Air and Moisture Valves for Internal-Combustion Engines; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skllled in the art to which it appertains to make and use the same.

This invention relates generally to internal combustion engines, and more particularly to certain new and useful improvements in auxiliary air and gas valves used in connection with the same.

The primary object of the invention is to provide a valve of this character wherein the use of springs and rubber or fiber packing washers are dispensed With.

Another object of the invention is to provide means whereby the water of condensation which may from time to time collect within the valve, may automatically drain out of the same.

A further object of the invention is to provide a unique form of stop for limiting the movement of the movable valve member.

A still further object of the invention is to generally improve upon valves of this character by providing a device which will be of extremely simple, durable and inexpensive construction, one which is eflicient and reliable in operation, and well adapted to the purpose for which it is designed.

With these and numerous other objects in view, the invention resides in certain novel features of construction, and the combination and arrangement of parts as will be hereinafter fully described and claimed. In the accompanying drawings, forming a part of the application, and in which similar reference characters designate like parts throughout the several views,

Figure 1 is a front elevation of a device constructed in accordance with this invention, showing the manner in which it is connected to the intake manifold of an internal combustion engine and to the air or steam space of the radiator of the engine;

showing the valve view taken Referring more particularly to the drawings, the numeral 1 represents a cylindrical valve chamber having a wall 2 at one end thereof provided with a centrally arranged circular opening 3 therein. The other end of the chamber 1 is reduced and externally threaded as at 4 and provided with a notch 5, the purpose of which will be hereinafter described. Projecting from the diametrically opposite sides of the chamber 1 are hollow stems 6 and 7, the stem 6 being externally threaded to adapt it for connection to the intake manifold A of an internal combustion engine, while the stem 7 is internally threaded to receive one end of a suitable pipe-section 8 leading from the steam or air space of the radiator B of the engine. These hollow stems communicate with the interior of the chamber.

Arranged within the chamber 1 is a cylindrical valve 9 having an opening extending transversely therethrough and communicating with the inner open ends of the hollow stems 6 and 7 The inner end of the valve 9 is held in frictionally tight contact with the interior side of the wall 2 of the chamber 1 by means of a disk 10, which is arsectional view taken of the chamber 1 and adjusted until the interior parts of the valve are in frictionally tight engagement. The valve 9 is thus held sufliciently tight against the wall 2 of the chamber '50 as to prevent leakage through the opening 3 in said wa1l,rand the valve 9 itself is sufiiciently tight in the chamber to also prevent such leakage.

In order to drain the Water or condensation which may from time to time collect in to the interior of the casing between the ends of the valve and the disk 10. This water then passes through an aperture 15 arran ed in the disk 10 into the space formed etween the other side of said disk and the interior side of the cap 13, and from there it will slowly drain through the opening 16.

The inner side of the disk 10 is provided with an annular channel 17 which assists in conveying the water to the aperture 15.

Extending longitudinally and centrally from the inner end of the valve 9 is a shank 18, the inner end of which is provided with a plurality of circumferentially spaced transversely extending ribs or ridges 19, while the outer end of the shank 18 is reduced a small amount in diameter and externally threaded to receive a clamping nut 20, between the inner end of which and the exterior side of the wall 2 is disposed the hub portion 21 of an operating arm or lever 22. This hub portion 21 of the arm 22 is provided with diametrically opposite pins or lugs 23 which are received in two of the longitudinal ridges 19 to prevent the arm from rotating with respect to the washer.

This construction of valves allows for mounting the arm in any radially extending direction with respect to the shank. This will be found advantageous when the valve is being connected to the operating devices to be hereinafter described.

The arm 22 is provided with a series of apertures 24:, one of which is to be connected in any convenient manner to one end of a link 25, the other end of the latter being connected in; any convenient manner to the throttle lever of the engine. Thus, whenever the throttle lever is actuated,-the'valve 9 is revolved a sufiicient amount to either open or close the passage extending transversely therethrough into communication with the inner open ends of the stems 6 and scribed other than as claimed.

naaaeee 7, depending upon which way said lever-is operated.

Extending longitudinally from the outer end of the valve '9 at a point offset a short distance from the longitudinal axis of the '70) same is a pin 26 which is received in a notch 27 arranged at one edge of the disk 10 to limit the movement of said valve. Rotation .of the disk 10 is prevented by the lug 28 a more extended explanation. As numerous changes in form, proportion, and in the minor detalls of construction may be resorted to without departing from the spirit of this invention, I do not wish to be limited to the construction herein shown and de- A device of the class described compris- 1ng a cylindrical valve chamber having a wall at one end thereof provided with a centrally arranged opening, and its other end open and externally threaded, hollow stems pro ecting from the diametrically apposite sides of said chamber, one of said stems bemg ada ted to be attached to the intake manlfol of an internal combustion engine, the other stem being adapted to be connected to the air space of the radiator, a rotary valve mounted within said chamber and havmg a passage extending transversely therethrough to communicate with the inner open 0 ends of said stems, a shank projecting longitudmally from the central portion of said valve and extending through said opening and provided with an arm adapted to be operatlvely connected with the throttle lever 5 of said engme, said valve being provided wlth a drain passage communicating with the lower side of the transverse passage therein for conveying the water of condensation from the same, a disk non-rotatably 2o mounted in said chamber and having centrally arranged outwardly projecting portions on 1ts opposite sides, the projecting portion on its inner side being disposed in tight contact with the outer end of said valve, and a cap threaded upon the open end of said chamber, the inner side of said cap bearing against the projecting portion on the outerside of said disk to hold the inner end of the valve into friotionally tight engagement with the interior side of the wall of said chamber, said disk and said cap being provided with apertures arranged substantially in communication with the lower end of the drain passage in said valve to provide a means for draining 0E the water of condensation collected therein.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
